IMPROVELIENT IN HOLDING SASH-WEIGHTS.

The Schedule referred to in these Letten Patent and'making part of the name.

To dll 'whom it may concern Be it known that I, WILLIAM W. Pumas, of the city and county of St. Louis, State of Missouri, have invented a new and improved Mode or Method of Molding Sash-Weights vertically; and4 I do hereby de- 'struction and operation.

I constructmy nowel F and cope C of either wood or iron, and of any desirable depth, using patterns P P P, &c., of any shape required. I laml them up in the sand in the nowel F, .as shown in fig. 1; .the loose sand then being brushed from between the patterns on the top of the uoivel, ldmw out the patterns; then, the top of fsand in nowel being inegular and uneven, I insert iu the molds the plugs H and K, with flanges of metal or Vother suitable substance; I then place on the cope, insert the gates, and ram the eope'with sand, the flexible nature of the substance need as a parting allowing the sand of cope to follow the irregulan'ties of sand in nowel. The operation is then in the condition as indicated in g 2; I then withdraw my gates, lift off my cope, and withdraw from the molds the plugs H-and K, cut my channels to conduet the metal, and the molds aneready topnnr.

The advantages of this method over all others are,V

as follows:

I secure a sash-weight, of any length or weight desilable, with a smooth clean end, .ofv any desirable shape, molded off ot one set of patterns. As in ram-- ming the patterns vertically in the uowel, with their vends projecting above the top of 'the same, it is not practicable to obtain a plane surface parting, by using the device mentioned above, the sand in cope follows the irregularities of the sand in the nowel, thereby making a perfect part or joint between sand .of cope and nowel after they are closed. I pour any convenient number o'f sash-weights from one gate, and so simplify the old method that a-common laborer can perform the work.

Claim The plugs H and K, constructed and arranged in relation to the nowel and cope, as set forth.
